Any BMW junkies out there? Paint code question

Learned to paint at Manscini’s, where I interned for 2yrs, did the Vo-Tec thing as well, then moved on to painting at Stanita Customs, Princetown auto body, and KME, along with doing side jobs here and there. The trade used to be fun, and could make a decent buck doing it, but insurance companies have since fucked that for us. The money is in restorations, but there isnt a huge market for it in Ny like there is elsewhere… So I got out of the field. Have about 8yrs of experience though.
